What is the best-selling disco song of all time?

Everyone's got an opinion about disco. Love it, hate it, or pretend you're too cool to care – disco's been pushing buttons since polyester was in fashion.

You may even recall Disco Demolition Night, when a promo for a Chicago White Sox game in 1979 got a bit out of hand. After blowing up a crate full of disco records, fans stormed the field and it turned into a full-on riot. Talk about a dance floor disaster!

And yet, for all the hate, everyone and their mother was secretly getting down with the sequined stylings of the disco artists of the day. It was like a guilty pleasure before we even knew what that meant. Let's face it – practically every major pop star of the time put out some kind of disco-influenced music. They couldn't help themselves. The beat was just too damn catchy. Even rock gods like Rod Stewart and KISS hung up their leather for a hot minute to join the glitter revolution.

And it wasn't just the music. Disco invaded every aspect of life. From fashion to film, it was everywhere. John Travolta pointing at the sky became the universal symbol for "I'm about to tear up this dance floor, and I don't care who's watching." People were installing disco balls in their living rooms like they were essential home appliances. If you didn't own at least one piece of clothing that could blind someone in direct sunlight, were you even living?

You can probably find a disco night right now somewhere in your town. Those mirror balls keep on spinning, and the platform shoes keep on stomping. Disco Demolition Night may have won the battle, but the groove definitely won the war.

And let's not forget the lasting impact. Disco didn't just disappear; it evolved. From Madonna to Daft Punk, from Bruno Mars to Dua Lipa, disco's fingerprints are all over the charts. It's the gift that keeps on giving, like a glitter bomb that exploded in the '70s and is still raining down on us today.

Need more proof that disco's still alive and kicking? One song was so successful it not only helped cement disco's place in music history, but also still gets played at everything from weddings to sporting events.

So, put on your dancing shoes and get ready to boogie down memory lane as we ask: Which disco tune took the world by storm, sold the most records, and became an enduring symbol of the genre's widespread appeal?

Hold onto your platforms because we're about to take a groovy detour into the world of eurodisco!

While "Y.M.C.A." may reign supreme as the best-selling pure disco hit, across the ocean, Europeans were busy cooking up their own disco inferno. Enter eurodisco: disco's glamorous cousin that traded in horn sections for synthesizers and made a sound all its own.

One of eurodisco's biggest hits, "Yes Sir, I Can Boogie" by Spanish duo Baccara, sold over 16 million copies worldwide. Yes, that's even more than "Y.M.C.A."! This 1977 success topped charts in 10 European countries and held the Guinness World Record for best-selling single by a female group for years.

And Eurodisco didn't just imitate American disco. Acts like Boney M., ABBA, and Giorgio Moroder put their own spin and brought a distinctly European flavor to the disco scene.

And talk about staying power! Eurodisco hits keep finding new life decades later. "Yes Sir, I Can Boogie" became an unlikely sports anthem for the Scottish national football team and sparked a TikTok dance challenge in 2020.

So next time you're at a 70s night, throw in some eurodisco. Just don't blame us if you end up practicing your German accent while doing The Hustle!
